Application mea May 7,1881. serial No. 231,475. (No model.)

To @ZZ whom it may concern:

Be it known that I, J ULIUs L. KNIEPER, a citizen of the United States, residing at the city of Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Chairs, of which the following is a specification.

My invention relates to a chair having rockers adapted'tobe adjusted vertically within the chair-legs and to be locked in'such positions by the mechanism hereinafter fully described; and the object of my invention is to adapt thechair to be used as a rocking-chair when its rockers are lowered and as an ordinary chair when the rockers are raised. Y These objects I accomplish by means of the mechanism illustrated in the accompanying drawings, in Which- Figure l is a perspective view of my invention in such a position as to show the device for attaching the chair-seat to the `bottom of the chair. Fig. 2 is a side elevation of one'of my rockers, showing my preferred method of n attaching the same to the legs of the chair. Fig. 3 is a side elevation of therocker with two of the chair-legs in the position they occupy with reference to the rocker when the chair is not used as a rocking-chair; and Fig. 4

is a side elevation ofthe same parts shown in Y. Fig. 3, with the rocker secured in position to be used with the chair as a rocking-chair. The attachment and adjustment of the two rockers vare identical.

shown 'at K K K, for the reception of theifreely in each slot, and they are of such shape that the pins may be locked in the upper part of the slots, thereby securing `the rockers in the position shown in Figs. l and 4.

D D are eccentric-levers adapted to turn on.

bolts or pins, and when turned down, as shown in Figs. l and 4, topre'ss against the leg of the chair and lock the pins in the upper part 'of the slots E. In the drawings I have shown but two of these eccentric-levers, as. one lever fo each rocker is all that is required. f

` I am not aware that any-chair has been made Vprior to my invention with slotted legs for the reception-of the rockers and of such size as to allow the rocker to be adjusted vertically .so v

within the'slot in order to convert the chair l from an ordinary chair into a rocking-chair at pleasure.

Having thus described my invention, what I Letters Patent, is-'- 1. In a chair of the class described, the combination of the legs having vertical slots and pins I I, the rockers provided each with the openings E E, said rockers adapted to be vertically adj usted in the slots in the rockers, and the pins adapted to engage with the upper part of the openings E E in the rockers, sub stantially as described.

2. In a chair of the class described, the combination of the vertically-slotted legs, the pins I I, the rockers provided withA openings E E, the eccentric-levers D D, for locking the rockers, substantially as described. f
